l .un OPENER.

This invention relates to jar openers of the type having a handleportion and a band thereon-adapted to surround a jar4 cover and to bedrawn into tight engagement therewith. I am aware that many ar openersof this type have been devised. ll such openers, however, as far as `Iam aware, do not ip the jar cover tightly except when the giind is heldin tight engagement by a manual force exerted on the iandle ortion ofthe opener. It is the primary ob]ect of my invention to provide a jaropener embodying means for drawing the band into tight engafrement abouta jar cover and securely holding the same in such osition.

It is a further object o my invention to rovide a jar opener embodylngmeans for Idrawing the band into tight engagement about a jar cover andother means co-operating therewith for holding the band'so engaged andsimultaneously therewith further tightening the band.

In the accompan ing drawing I have illustrated one speci c embodiment ofmy invention, 'but it will be understood that lthe Y invention can beotherwise embodied and that the drawin is'not to be construed asdefining or limiting the scope of the invention, the claims appended tothis specicationbeing relied upon for that urpose.

Referring to the figures of t e drawing .Fig 1 is a side elevation of myimproved jar opener, showing the Ihandle portion thereof in section andthe band thereof in place on a jar cover;

Fig. 2 isa plan view thereof, partially in section.

Referring more specifically to the drawing by reference characters, lindicates a piece of brass tubing, rectangular in cross-section, whichforms the main handle Aportion of my improved jar opener. (3o-operatingtherewith is a steel band 2 adapted to surround a jar cover 3. The endsof this 'band are secured to a block 4 slidably mounted in .the handle1, the band extending to the opposite sides of a brid e piece 5secured-in the end of the handle screws 6. A toothed rack 7 is securedto t 1e block 4 as illustrated.

A pinion 8 on a shaft '9 carried by the plates 10 secured to the sides`of the handle is in mesh with the rack 7, an operating knob 11 beingprovided on the shaft. A pinionengaging slide'12 is connected bv a screw13 to a stud 14 mounted inthe handle 1. Rota- Applioation iled A pril27, 1925. Serial No. `138,056.

tionof the'screw is adapted to move the slide into and out yofengagement with the pinion.

n is believed that the parution andadvantages of my invention will beclear without further description herein. "The resiliency of the band 2is suchthat it normally s reads out to its full opening, thereby rawingthe block 4 to the` extreme left end of the handle 1. `In operation theband is placed over a coverto be removed and the shaft 9 rotated in thedirection of the arrow to draw thel block inwardly and close the bandonto the cover. When the band is in tight engagement with the cover thescrew 13 is rotated to engage the plate 12 with the pinion. As seen inFig. 1, the plate engages a pinion tooth above the pinion axis in amanner to not only hold the pinion against backward rotation but tofur-ther rotate the same in the direction of the Aarrow. Thus thisrotation of the screw not only holds the band-tightly enga ed with thecover, but serves to further tig ten theple and cheap to manufacture andthe o c eration vthereof is most eicient. rllhe resi iency of the band 2normally holds the de- Y vice in the wide open position for engaging thelargest size covers. Covers of any size from the largest to the smallestcan be engaged and removed with like efficiency. Furthermore, theoperation thereof requires no hard hand gripping .of the handle portion,as do most jar openers, and when once in position on a cover, the openeris securely eld in such position until removed by releasing the screw13.

, Having thus described my invention, what I, claim as new and desire tosecure by LettersPatent is 1. A jar opener comprising the combination ofa handle, a member movably carried thereby, a band connected to themember and adapted to surround a jar cover, means on the handle formoving the member to' draw ico the band tightly about the cover, andmeans for holdingthe band so drawn and thereafter further tightening theband and simultaneously therewith holding t-he same against loosening,the band tightening and holding means being movable relative to thehandle in the said band tightening and holding operations. l

2. A jar opener comprising the combination of a handle portion, a bandconnected thereto and adapted to surround a jar cover, rotary means fordrawing'the band tightly about the cover, means operative on the rotarymeans to hold the same in the bandtightened position, and cooperatingmeans to further tighten the band relative to the handle.

3. A jar opener comprising the combination of a handle portion, a bandconnected thereto and adapted to surround a jar cover, rotary means fordrawing the band tightly about the cover, and means operative on therotary means to further tighten the band and hold the same in itstightened position.

4. A jar opener comprising the combination of a handle, a toothed racktherein, a band connected to the rack and adapted to surround a jarcover, a'pi'nion engaging the rack and adapted upon rotationy in onedirection to tighten the band on the cover, and means for engaging thepinion to rotate the same in the said band tighteningdirection.
